ATTENTION

Before Using the Phone:

It is necessary that you CHARGE your phone

battery fully before attempting to make or receive a call.

Battery Disposal:

DO NOT PLACE USED BATTERIES IN YOUR REGULAR

TRASH. THIS NICKEL-CADMIUM (Ni-Cd) BATTERY MUST

BE COLLECTED, RECYCLED OR DISPOSED OF IN AN

ENVIRONMENTALLY SOUND MANNER.

Battery Recommendations:

The NEC TalkTime MAX™ 920 cellular phone you have

purchased was designed to deliver quality performance and

provide you with years of use. In order to maintain optimum

performance, NEC recommends that only NEC Authentic

Accessories™ be used with the TalkTime phones.

Specifically, NEC recommends only the use of Nickel

Cadmium (NiCd) batteries with the TalkTime MAX™ 920

phone. Use of other batteries, such as Nickel Metal Hydride

(NiMH) may result in poor battery performance, and in some

cases, create a potential safety risk due to overheating of the

battery.

The incineration, landfilling or mixing of nickel-cadmium

(Ni-Cd) batteries with municipal solid waste stream is

PROHIBITED BY LAW in most areas.

Return this battery to a federal or state approved nickel-

cadmium (or “sealed lead”) battery recycler. This may be

where you purchased the battery or a local seller of

automotive batteries. In all states, call 1-800-822-8837,

except Minnesota if further disposal information is required.

In Minnesota, call 1-800-225-PRBA.

Contact local waste management officials for other

information regarding the environmentally sound collection,

recycling and disposal of this battery.

In-Vehicle Operation:

For In-Vehicle Operations, the phone battery must be

charged, since In-Vehicle Adapter Kits serve only as a trickle

battery charger.

IMPORTANT

READ THIS INFORMATION BEFORE USING

YOUR HAND-HELD PORTABLE CELLULAR

TELEPHONE

First introduced in 1984, the hand-held portable cellular

telephone is one of the most exciting and innovative

electronic products ever developed. With it you can stay in

contact with your office, your home, emergency services, and

others.

For the safe and efficient operation of your phone, observe

these guidelines.

Your cellular telephone is a radio transmitter and receiver.

When it is ON, it receives and also sends out radio frequency

(RF) energy. The phone operates in the frequency range of

824 MHz to 894 MHz and employs commonly used

frequency modulation (FM) techniques. When you use your

phone, the cellular system handling your call controls the

power level at which your phone transmits. The power level

can range from 0.006 of a watt to 0.6 of a watt.

Exposure to Radio Frequency Energy

In 1991 the Institute of Electrical and Electronics Engineers

(IEEE), and in 1992 the American National Standards

Institute (ANSI) updated the 1982 ANSI Standard for safety

levels with respect to human exposure to RF energy. Over

120 scientists, engineers, and physicians from universities,

government health agencies, and industry, after reviewing the

available body of research, developed this updated Standard.

In March, 1993, the Federal Communications Commission

(FCC) proposed the adoption of this updated Standard.

The design of your phone complies with this updated

Standard. Of course, if you want to limit RF exposure even

further than the updated ANSI Standard, you may choose to

control the duration of your calls and operate your phone in

the most power efficient manner.

Efficient Phone Operation

For your phone to operate at the lowest power level,

consistent with satisfactory call quality, please observe the

following guidelines:

iii

If your phone has an extendable antenna, extend it

fully. Some models allow you to place a call with the

antenna retracted. However, your phone operates more

efficiently with the antenna fully extended.

Hold the phone as you would any other telephone. While

speaking directly into the mouthpiece, position the antenna

up and over your shoulder. Do not hold the antenna when

the phone is “IN USE.” Holding the antenna affects call

quality and may cause the phone to operate at a higher

power level than needed.

Antenna Care and Replacement

Do not use the phone with a damaged antenna. If a

damaged antenna comes into contact with the skin, a minor

burn may result. Replace a damaged antenna immediately.

Consult your manual to see if you can change the antenna

yourself. If so, use only a manufacturer approved antenna.

Otherwise, take your phone to a qualified service center for

repair.

Use only the supplied or approved antenna. Non-approved

antennas, modifications, or attachments could impair call

quality, damage the phone, and violate FCC regulations.

Driving

Check the laws and regulations on the use of cellular

telephones in the areas where you drive. Always obey them.

Also, when using your phone while driving, please:

* give full attention to driving,

* use hands-free operation, if available, and

* pull off the road and park before making or answering

a call if driving conditions so require.

Electronic Devices

Most modern electronic equipment is shielded from RF

energy. However, RF energy from cellular telephones may

affect inadequately shielded electronic equipment.

iv

RF energy may affect improperly installed or inadequately

shielded electronic operating and entertainment systems in

motor vehicles. Check with the manufacturer or its

representative to determine if these systems are adequately

shielded from external RF energy. You should also check

with the manufacturer of any equipment that has been added

to your vehicle.

Consult the manufacturer of any personal medical devices

(such as pacemakers, hearing aids, etc.) to determine if they

are adequately shielded from external RF energy.

Turn your phone OFF in health care facilities when

any regulations posted in the areas instruct you to do so.

Hospitals or health care facilities may be using equipment

that could be sensitive to external RF energy.

Aircraft

Turn your phone OFF before boarding any aircraft.

* Use it on the ground only with crew permission.

* Do not use it in the air.

To prevent possible interference with aircraft systems,

Federal Aviation Administration (FAA) regulations require you

to have permission from a crew member to use your phone

while the plane is on the ground. To prevent interference

with cellular systems, FCC regulations prohibit using your

phone while the plane is in the air.

Children

Do not allow children to play with your phone. It is not a toy.

Children could hurt themselves or others (by poking

themselves or others in the eye with the antenna for

example). Children also could damage the phone, or make

calls that increase your telephone bills.

Blasting Areas

To avoid interfering with blasting operations, turn your unit

OFF when in a “blasting area” or in areas posted:

“Turn off two-way radio.”

Construction crews often use remote control RF devices to

set off explosives.

Air Bags

An air bag inflates with great force. DO NOT place objects,

including both installed or portable wireless equipment, in the

area over the air bag or in the bag deployment area. If in-

vehicle wireless equipment is improperly installed and the air

bag inflates, serious injury could result.

v

Potentially Explosive Atmospheres

Turn your phone OFF when in any area with a potentially

explosive atmosphere. It is rare, but your phone or its

accessories could generate sparks. Sparks in such areas

could cause an explosion or fire resulting in bodily injury or

even death.

Areas with a potentially explosive atmosphere are often, but

not always, clearly marked. They include fueling areas such

as gas stations; below deck on boats; fuel or chemical

transfer or storage facilities; areas where the air contains

chemicals or particles, such as grain, dust, or metal powders;

and any other area where you would normally be advised to

turn off your vehicle engine.

Do not transport or store flammable gas, liquid, or explosives

in the compartment of your vehicle that contains your phone

or accessories.

Vehicles using liquefied petroleum gas (such as propane or

butane) must comply with the National Fire Protection

Standard (NFPA-58). For a copy of this standard, contact

the National Fire Protection Association, One Batterymarch

Park, Quincy, MA 02269, Attn: Publication Sales Division.

Pacemaker/ICDs

Research sponsored by the Wireless Technology Research,

LLC (“WTR”), indicates that some wireless telephones cause

interference with pacemakers. Accordingly, NEC America

endorses the following recommendations issued by the WTR:

Wireless phones should be kept at a safe distance from a

pacemaker. Existing data indicate that the greater the

distance between a pacemaker and a wireless phone, the

less risk of interference. These data further indicate that six

inches is the proper separation distance for minimal risk.

Practical steps to achieve this separation distance include:

o The wireless telephone should not be placed over the

pacemaker, such as in a breast pocket, when it is in the

“ON” position. (A phone is “ON” when power is being

supplied to the telephone by the battery.)

o The phone should be used at the ear opposite the

pacemaker.

Note: There is nothing in the comprehensive data to

suggest that bystanders with pacemakers would be at risk of

interference from others who are using wireless phones.

ROAMING (SYSTEM SELECT)

Each cellular service area can have two cellular service

suppliers called carriers. One carrier is called the ‘non-

wireline’ or ‘A’ system and the other carrier is called the

‘wireline’ or ‘B’ system. Your phone is designed to work with

either or both carriers.The system priority feature allows you

to program your phone for optimum operation when in your

home serving area or when away from your home area. This

is called roaming. When you buy your phone, you may

register (receive a phone number) with either or both of your

PWR

local carriers. Contact the office of your home cellular phone

company for information about the roaming agreements they

have with other cellular phone companies. In some areas,

roaming telephones are automatically recognized by the

cellular system’s computer. In other areas, you must contact

the cellular phone operator before it can recognize your

your phone ESN (electronic serial number), and how you

plan to pay for your calls. There is usually an additional

charge for roaming calls.

This allows the phone to first search for a free channel

in the Home system. If the phone cannot find a free

channel, it searches the other system.

The ROAM indicator is displayed when the phone is using a

system other than your home system. The roam systems

your phone accesses can be specified through the use of

system identification management, referred to as SID

management. SID Management is described below.

SID MANAGEMENT

The SID Management feature lets the phone operate only

within specifically identified (Preferred) systems. The service

provider can enter up to thirty (30) preferred System ID

numbers that identify the systems that you want your phone

to access.

Programming of your System ID numbers is accomplished

by your service provider and is only associated with NAM1.

DTMF TONE

The DTMF Tone generator has two settings, Standard and

Long. If the DTMF Tone generator is set to Standard, the

phone sends each DTMF signaling tone for 100 milli-

seconds. With the DTMF Tone generator set to Long, the

phone sends each DTMF signaling tone for as long as the

key is pressed, up to 3 seconds maximum.

VOICE MESSAGING SERVICE

Cellular Digital Messaging Service (CDMS), if available

through the cellular service provider in the area, is a voice

message service for the cellular customer. When a cellular

customer turns off or does not answer the cellular phone, or

when the customer is currently on a call, CDMS answers the

incoming call. The caller is provided with the option to leave

a voice mail message. The cellular phone user is notified of

messages through a voice mail message indication.

VOICE MAIL MESSAGE INDICATION

When an incoming caller leaves a message through the

cellular provider's digital messaging service, the cellular

phone user is notified by a voice mail message indication.

The type of voice mail message notification varies between

cellular service providers. Upon receiving a voice mail

message, the voice mail message indication is one of the

following: a phone beep and displayed “MAIL” indication, a

phone beep without a displayed indication, or a series of

beeps generated by the service provider and transmitted to

the phone user through the earpiece receiver when an

outgoing call is made. The displayed indication is shown

below.

If additional messages are received before the current voice

message information is retrieved, the voice mail message

number in the displayed indicator increases.

Voice messages can be retrieved from the messaging

service by following the service provider instructions for voice

message retrieval. Contact your service provider for

information on availability of voice messaging services and

for any additional information on voice mail messaging.
